Title: Liquid fatty component containing composition
Inventor: RITTER HEIKE
IPC: A23L27/60
Filed: 1997-05-12
Abstract: It was found that by the addition of 2 different, specific sterols, which preferably are phytosterols, to a liquid fat, the liquid fat was no longer liquid, but showed a firmness, measured as Stevens hardness, significantly higher than that of the liquid fatty compound itself. Preferably, the liquid fat is an edible fat, and the sterols used is a mixture of phytosterols, preferably oryzanol and sitosterol at a minimum total weight level of 2 %, preferably 4 %, with a clear optimum at a molar ratio between 3:1 and 1:3, further preferred between 1:2 and 2:1. The composition is preferably used in consumer goods, such as cosmetic products or food products. Also these products comprising such a composition are part of the invention. After dissolution of the sterols in the fatty compound at elevated temperature, improvement of structuring capacity of the sterols was found by rapid cooling.

Title: Cellular system hand-off protocol
Inventor: SMITH DOUGLAS A
IPC: H04L12/28
Filed: 1997-06-19
Abstract: A cellular communication system hand-off protocol which helps minimize down time associated with a mobile device roaming among different cells in which different cells employ different communication channels (e.g., different frequency hopping sequences). In a preferred embodiment, each base station is configured to communicate its own particular hopping sequence to all other base stations via the system backbone. Each base station then provides to mobile devices which are registered thereto information regarding the particular hopping sequences employed by other base stations servicing cells into which the mobile device may roam. Such information includes the particular hopping sequences together with an indication of what location in the sequence the base stations are currently at in any given time. In addition, such information may include an indication of the intervals at which a base station is configured to transmit a beacon packet (for passive scanning operation), or at what intervals test pattern packets are transmitted to allow for signal quality evaluation.

Title: A method for porting a mobile directory number from one wireless service provider to another
Inventor: ROLLENDER DOUGLAS HAROLD
IPC: H04M3/00
Filed: 1999-02-09
Abstract: The present invention is a method for porting a mobile directory number of a subscriber from a donor wireless service provider to a recipient wireless service provider with minimum interruption to the subscriber's wireless communication service. In one embodiment, the present invention is accomplished by creating an entry for the wireless terminal in the recipient wireless service provider's home location register and a temporary pointer in the donor wireless service provider's home location register, wherein such temporary pointer will cause the donor wireless communication system to route or forward any call intended for the wireless terminal being ported to the recipient wireless communications system for completion in well-known fashion. When the porting process is complete, the temporary pointer is removed or deactivated in the donor wireless service provider's home location register.  Advantageously, coordination of the porting process is controlled by the recipient wireless service provider resulting in minimum interruption to the subscriber's wireless communications service.

Title: Mobile communication apparatus uplink message transmission of battery output level information
Inventor: LUONG ALBERT
IPC: H04W52/02
Filed: 1997-12-09
Abstract: A mobile communications apparatus (10) monitors (26) the power level of its internal battery (24) power supply, and reports (46) the measured power information on a periodic basis to a serving network. These reports are preferably made during the course of an ongoing call communications utilizing an uplink communications channel (112). The reported power information is stored by the network. In response to a subsequent detection (142) of an instance of a call drop with respect to that mobile communications apparatus, the stored reported power information is retrieved (144) and processed (146) to determine whether failure of the battery for the mobile communications apparatus is a likely cause of the call drop. If such is the determination, that fact is noted (148) in association with recording the instance of the call drop as the drop cause.
